sensor system and method for detecting the axles of trains using fiber optics and cameras flight time

Sensor device and method for detecting the axles of trains, using fiber optics and cameras flight time. The device is basically constituted by a time of flight camera (1), an infrared light emitting center of (2) and an optical fiber bundle (3). The procedure is based, from the information provided by camera flight time, focused to a terminal harness fiber optic wheel information and determine the instant passing the center thereof. The infrared light emitting source of is used to illuminate the scene through a terminal harness optical fiber. Using fiber optic harness can illuminate and capture 3D images at great distances from the camera flying time and infrared light emitting source, being able to locate them away from the road.
